Quorum sensing in group A Streptococcus [PDF]
Frontiers in Cellular and Infection Microbiology, 2014 Quorum sensing (QS) is a widespread phenomenon in the microbial world that has important implications in the coordination of population-wide responses in several bacterial pathogens. In Group A Streptococcus (GAS), many questions surrounding QS systems remain to be solved pertaining to their function and their contribution to the GAS lifestyle in the ...

Information processing and signal integration in bacterial quorum sensing [PDF]
, 2009 Bacteria communicate using secreted chemical signaling molecules called autoinducers in a process known as quorum sensing. The quorum-sensing network of the marine bacterium {\it Vibrio harveyi} employs three autoinducers, each known to encode distinct ...

LuxS and quorum-sensing in Campylobacter [PDF]
Frontiers in Cellular and Infection Microbiology, 2012 Several intercellular bacterial communication mechanisms have been identified in a broad range of bacterial species. These systems, collectively termed quorum-sensing systems, have been demonstrated to play significant roles in a variety of bacterial processes including motility, biofilm formation, expression of virulence genes, and animal colonization.

More Bang For Your Buck: Quorum-Sensing Capabilities Improve the Efficacy of Suicidal Altruism [PDF]
, 2014 Within the context of evolution, an altruistic act that benefits the receiving individual at the expense of the acting individual is a puzzling phenomenon. An extreme form of altruism can be found in colicinogenic E. coli.

Phenotypic memory in quorum sensing
PLOS Computational Biology, 2023 Quorum sensing (QS) is a regulatory mechanism used by bacteria to coordinate group behavior in response to high cell densities. During QS, cells monitor the concentration of external signals, known as autoinducers, as a proxy for cell density. QS often involves positive feedback loops, leading to the upregulation of genes associated with QS signal ...

Breaking down bacterial communication: a review of quorum quenching agents
Future Journal of Pharmaceutical Sciences, 2023 Background Bacterial cells communicate via small extracellular molecules that facilitate gene expression which is dependent on cell density and this mechanism is known as Quorum Sensing (QS).

Implications of Rewiring Bacterial Quorum Sensing [PDF]
, 2008 Bacteria employ quorum sensing, a form of cell-cell communication, to sense changes in population density and regulate gene expression accordingly.

Quorum sensing with pheromones [PDF]
Nature Microbiology, 2019 The vast majority of fungi reproduce sexually and use secreted pheromones to signal to each other. A study now shows that these signalling molecules in the fungal plant pathogen Fusarium oxysporum activate a density-dependent autocrine signal that controls asexual spore germination.

Quorum Sensing in Extreme Environments [PDF]
Life, 2013 Microbial communication, particularly that of quorum sensing, plays an important role in regulating gene expression in a range of organisms. Although this phenomenon has been well studied in relation to, for example, virulence gene regulation, the focus of this article is to review our understanding of the role of microbial communication in extreme ...
